Computer power supply?

If I have a mostly stock computer, the only change is that i upgraded to a 7600 gt video card. I don't know my current power supplies wattage but the guy at best buy said that the video card can run at it's best with 300 watts of power. Do I need to upgrade my power supply for this to be better.



Honestly I can't see how my computer could run any better but I am asking if anyone has changed their power supply and gotten better performance out of your video cardComputer power supply?
Power supply units run cooler and last longer if the load is 80% or less.



With the 36 watts of your 7600GT that you added, you could be running your power supply (or one of the rails) at or near maximum load. Stability issue may crop up later.



A bigger power supply will not improve the card's performance but could provide better reliability/stability over the longer term.Computer power supply?
if your video card is installed already and it runs fine and you dont plan to overclock the machine, you dont need a new powersupply. increasing the powersupply will not effect the cards performance.Computer power supply?
Power supplies are a tricky thing. It all depends on what you have inside running also:

Mobo-35-45w

CPU--Intel 45-95W AMD - 35-85W

Memory -- 7w per 128mb of memory.

Video card -- 27-75w

Hdd- 45w

DVD/RW/CD/RW- 50w

PCI cards 14-35w

10% more for adding components later....

Just @ least 300w to run the low end computers....

I have AMD Dual Core and 2*300gb hdds with 2 DVD Burners, only 256mb video, but 3gb of memory and not PCI cards and mine totalled around 467w needed but I opted for a 600w to insure future upgrades...ThanksComputer power supply?
Play a game that uses a lot of graphic power and see if it stalls.
